The AMU difference occurs because U-238, which is the most abundant naturally occurring uranium isotope, has three more neutrons in its atom than U-235. U-235 is used in nuclear reactors to generate nuclear energy by the process ofnuclear fission. It is also one of the key ingredients of ...
THE ATOMIC WEIGHT OF PROTACTINIUM His value of 207 for AcD leads by simple additions to 231 as the atomic weight of protactinium. On the basis of Aston's data Rutherford estimated the half-period of actino-uranium, the parent of the series, to equal 4路0 脳 ... A Grosse - 《Proceeding...
